opencv学习笔记（一） 使用opencv进行拍照

原理很简单，首先打开摄像头，new一个Mat容器来储存拍摄的照片，调用函数Imgcodecs.imwrite就可以将图像保存到对应位置，实现拍照的效果了。具体代码如下：

import org.opencv.core.*;import org.opencv.imgcodecs.Imgcodecs;import org.opencv.videoio.VideoCapture;             public class TakePhotos {static{ System.loadLibrary(Core.NATIVE_LIBRARY_NAME); }    public static void main (String args[]){    VideoCapture camera = new VideoCapture();    camera.open(0);    if(!camera.isOpened()){    System.out.println("Error");    }    else {    Mat frame = new Mat();        try {        System.out.println("准备拍照");        camera.read(frame);        Imgcodecs.imwrite("路径//cameraTakeApicture.jpg", frame);        System.out.println("拍照成功");} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}    }    camera.release();    }}
